From the DDN:

Pitcher David Weathers, who injured the index finger on his pitching hand playing catch in the offseason, was cleared Thursday by the medical staff for full participation.
“I did some long-tossing (Thursday), and I’ll be doing everything,” said Weathers. “I hoped I’d miss some PFP (pitchers fielding practice), but I won’t.”

This is good news. In a bullpen as iffy as this one, someone that was fairly solid most of the season would be missed.
